[00:01:42] <andypugh> Just use one of the servo configs from the CD
[00:02:06] <Jymmm> Administrator_: You shouldn't IRC as root/administrator
[00:02:21] <pfred1> Jymmm its probably their user account
[00:03:15] <Jymmm> pfred1: you cna't create "Admnistrator" or "Guest" under M$, those are reserved.
[00:03:32] <Jymmm> as is 'system'
[00:04:01] <pfred1> I see ppl IRC all the time as root they seem to live through the ordeal
[00:04:18] <Jymmm> They are ignorant
[00:05:05] <pfred1> I bet this servo would make a cool wind generator
[00:12:18] <andypugh> OK, time to cease
[00:15:00] <Administrator_> i'm your administrator, all hail me
[00:17:29] <JT-Hardinge> make my monitor work then
[00:19:41] <Administrator_> poof!
[00:19:47] <Administrator_> does it work?
[00:20:10] <Administrator_> Administrator_ is now known as aa-danimal-shop
[00:20:47] <JT-Hardinge> nope
[00:20:49] <aa-danimal-shop> not sure why it logged me on as administrator
[00:20:59] <aa-danimal-shop> weird
[00:21:08] <aa-danimal-shop> i was signed in under this name earlier
[00:23:15] <aa-danimal-shop> what monitor died?
[00:23:32] <JT-Hardinge> viewsonic
[00:23:46] <JT-Hardinge> fits in the trash better now
[00:24:40] <JT-Hardinge> time to cook!
[00:28:57] <pfred1> JT-Hardinge flat or tube?
[00:57:28] <Jymmm> JT-Hardinge: I have one of these LOVE IT!!! http://www.newegg.com/Product/Product.aspx?Item=N82E16824001317 All the reviews about the stand are bullshit, totally easy if you have half-a-clue (tm).
[00:58:29] <Jymmm> JT-Hardinge: Got it for like $239 It does 2048x1152 without needing Dual-DVI and the contrast ratio is 50,000 not 20,000.
[00:58:48] <Jymmm> JT-Hardinge: FULL two page layout at that res.
[00:59:54] <SWPadnos> that's a great monitor, isn't it
[01:00:17] <Jymmm> Yeah it is - great price too
[01:00:28] <SWPadnos> it looks like that resolution never caught on though (at least not at NewEgg) - they only had one Acer (at that res) in stock last week
[01:01:09] <SWPadnos> that's the monitor I use on the camera array, so I have the 7-desktop 3D rotation thing going with it
[01:01:36] <Jymmm> ah
[01:01:42] <SWPadnos> oh. the Acer is out of stock too
[01:02:06] <SWPadnos> it's the only active item at that res, and it's a $450 27" one
[01:02:28] <Jymmm> I waited a LONG LONG time to get an LCD becasue I wanted the 2048 (two page layout)
[01:03:08] <SWPadnos> yeah. I really like that monitor. the color seems very good, the swivel stand is nice, and it's a good size and price
[01:03:14] <SWPadnos> I should have bought a fwe more
[01:03:14] <pfred1> LCDs are a thing of the past now aren't they?
[01:03:19] <SWPadnos> har har
[01:03:29] <pfred1> isn't the new thing LED?
[01:03:41] <Jymmm> SWPadnos: Looks like it's been discontinued http://www.superwarehouse.com/Samsung_2343BWX_23_Widescreen_LCD_Monitor/2343BWX/p/1556488
[01:03:42] <SWPadnos> that's LED backlighting of LCD panels, not real LED displays
[01:04:06] <Jymmm> CCFL and EL backlighting are no longer
[01:04:07] <SWPadnos> there's only one LED monitor that I know of (that's actually for sale), and it's a Sony TV that's something like 11" and $2700
[01:04:14] <SWPadnos> OLED that is
[01:04:33] <MarkusBec> MarkusBec is now known as MarkusBec_away
[01:04:33] <Jymmm> ah
[01:04:34] <SWPadnos> eventually, OLED may replace LCD, but it'll be a while before it gets inexpensive enough for that
[01:04:53] <pfred1> well teh LCDs sure dropped in price pretty fast
[01:05:03] <SWPadnos> Jymmm, shows discontinued there as well :)
[01:05:20] <SWPadnos> yeah, 22" or so have been sub-$200 for a couple of years
[01:05:34] <SWPadnos> depending on other features, that is
[01:06:18] <pfred1> I bought one of these as a cheap HD TV for my bedroom: http://www.newegg.com/Product/Product.aspx?Item=N82E16824254043&cm_re=hanns_g_monitor-_-24-254-043-_-Product
[01:06:44] <SWPadnos> how's the image wuality?
[01:06:47] <SWPadnos> quality
[01:06:54] <SWPadnos> (if you've hooked it up to a PC)
[01:07:11] <pfred1> only thing that pisses me off about it is it bleeds through on the edges on a black screen other than that its OK
[01:07:32] <SWPadnos> ok, so the bezel doesn't "seal" the edges?
[01:07:32] <pfred1> nah i only use it to watch TV on
[01:07:37] <SWPadnos> hmmm. ok
[01:07:48] <pfred1> I guess its like a halo of light around the edges
[01:07:50] <SWPadnos> that looks like a reasonable monitor for my mother
[01:07:51] <SWPadnos> ok
[01:08:04] <pfred1> if there is anything on the screen you don't notice it
[01:08:20] <pfred1> but before i turn the set top boxo n and its black I can see it
[01:08:22] <SWPadnos> ok. she'd have the screen off if there's nothing on it ;)
[01:08:57] <pfred1> other than that its HD I wanted a smallish one so I didn't knock it over atthe foot of my bed
[01:09:41] <pfred1> but its not as vivid as the Samsung I have downstairs and it doesn't upscale either
[01:09:49] <pfred1> well if it does i never figured out how
[01:10:03] <SWPadnos> monitors without HDMI inputs rarely do that well
[01:10:10] <SWPadnos> and ones with HDMI it's a crapshoot
[01:10:26] <pfred1> this one has HDMI
[01:10:39] <SWPadnos> I didn't see it listed in the NewEgg description
[01:10:40] <pfred1> and thats all I use on it from the fios TV box
[01:11:05] <SWPadnos> oh wait, I was looking at the wrong description
[01:11:06] <pfred1> I donno maybe this isn't exactly the model I have then because mine has HDMI
[01:11:26] <SWPadnos> if only I could get fiber here
[01:11:47] <pfred1> yeah its amazing i can get it
[01:12:04] <SWPadnos> it would be easier in Korea
[01:12:08] <SWPadnos> (south)
[01:12:09] <pfred1> only reason is they said they were going to wire the whole exchange I'm in and they finally did it
[01:12:28] <pfred1> verizon guy I said they're not expanding at all it costs them too much
[01:12:42] <pfred1> its just not worth laying the cable now
[01:13:10] <pfred1> I sorta felt bad because the drop they had to run to me was over 900 feet
[01:14:05] <pfred1> but now that its done I don't feel so bad about it really
[01:14:07] <SWPadnos> that's a heck of a cable ;)
[01:14:32] <pfred1> yeah I got a pretty long driveway
[01:14:58] <pfred1> and they had to come from the far side of the property for some odd reason too
[01:15:43] <pfred1> that at least they attached to some old phone cables on the pole
[01:15:57] <pfred1> but down my driveway they buried it
[01:16:58] <pfred1> for a cheap TV to fall asleep to I guess the Hanns G is OK
[01:17:25] <pfred1> half the time I'm watchng it with my eyes closed anyways so I guess the picture is good enough for that :)
[01:18:05] <pfred1> I bet today you can find better for cheaper though
[01:19:04] <pfred1> oh the other annoying thing about it is no remote control but i use the set top box remote
[01:19:49] <pfred1> one more thing the speakers in it are a joke
[01:20:27] <LawrenceG> logger_emc, bookmark
[01:20:27] <LawrenceG> Just this once .. here's the log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2010-03-23.txt
[01:20:28] <pfred1> forgot about that I have it hooked to a 5.1 system
[01:21:40] <SWPadnos> monitor speakers are rarely useful
[01:21:53] <SWPadnos> speaking of which, I should go upstairs and watch a movie. see you
[01:21:55] <pfred1> well these made my skin crawl they were really bad
[01:22:00] <SWPadnos> or continue doing tax accounting
[01:22:15] <SWPadnos> nah. movie
[01:24:05] <skunkworks> what movie?
[01:29:19] <aa-danimal-shop> herbie the love bug
[01:30:17] <aa-danimal-shop> or the newer version with lindsey lohan... herpie the love bug
[01:36:31] <skunkworks> fight club
[01:40:22] <Eric_K> tautology club
[01:42:45] <aa-danimal-shop> chess club
[02:51:12] <cradek> haha, hugeurl.com
[03:02:10] <aa-danimal-shop> haha
[03:02:24] <WalterN> hi aa-danimal-shop
[03:02:49] <aa-danimal-shop> hi WalterN
[03:03:20] <WalterN> what kind of CNC mill do you have again?
[03:04:22] <aa-danimal-shop> shizuoka
[03:05:48] <pfred1> aa-danimal-shop gesundheit!
[03:05:59] <aa-danimal-shop> lol
[03:07:12] <pfred1> man I'm getting so stressed out drawing this symbol over here
[03:07:31] <WalterN> hmm
[03:07:46] <WalterN> aa-danimal-shop: what kind of CAD program do you use?
[03:08:41] <aa-danimal-shop> solidworks
[03:08:47] <aa-danimal-shop> and mastercam x for cam
[03:08:52] <WalterN> ok
[05:12:15] <elmo40> i loved solid works 2k4.
[05:12:24] <elmo40> tried 2k9, just didnt 'feel' the same
[05:13:15] <DaViruz> i was entirely lost in 2009, tried 2010 a few days back and i really liked the itnerface
[05:24:58] <elmo40> hrmm, that linuxcnc page for gcode should have G80 described as 'Cancel Canned Cycle' instead of 'Cancel motion mode'
[05:25:09] <elmo40> since g81, g85... are canned cycles.
[05:29:20] <elmo40> now, if only free-cad.sf.net would have an interface as solidworks 2k4 ;)
[08:00:13] <anonimasu> PCW: hello did you compile the bitfile yet?
[08:05:09] <SWPadnos_> SWPadnos_ is now known as SWPadnos
[08:54:19] <anonimasu> pcw_home: did you compile the bitfile?
[08:54:21] <pcw_home> anonimasu: yes
[08:55:19] <anonimasu> awesome
[08:55:35] <pcw_home> You might need 2.4 pre or whatever its called since the bitfile uses a rev3 IDROM
[08:55:35] <anonimasu> how can I get ahold of it?
[08:56:07] <anonimasu> I see
[08:56:27] <anonimasu> did you put it in the cvs?
[08:58:44] <pcw_home> its on our website (with 5M glob of 7I43 stuff)
[08:58:46] <pcw_home> (its not in CVS)
[08:58:48] <pcw_home> If you send me an email pcw@... Ill bounce you back the bitfile
[09:01:44] <anonimasu> done
[09:05:28] <anonimasu> pcw_home: tell me if it works, my mail sometimes dosent work so great
[09:05:55] <pcw_home> nothing yet
[09:10:35] <pcw_home> bbl
[09:27:09] <GoTschA_> GoTschA_ is now known as GoTschA
[09:32:09] <piasdom> g'mornin all
[12:14:29] <MattyMatt> why aren't coils made with square wire anymore? I've never seen one but this 1910 pop mech has a table of them
[12:16:51] <MattyMatt> afaics they'd be 4/pi more efficient
[12:52:24] <MattyMatt> woohoo UK Space Agency has been formed, appropriately on Apr 1st
[12:53:22] <MattyMatt> all those unemployed people can help to wind the elastic
[12:53:30] <MattyMatt> 'those' = me
[13:08:50] <anonimasu> did anyone implement thc with classicladder?
[13:09:11] <anonimasu> how do you still make the axis able to have a position loop?
[13:11:12] <MrSunshine> hmm, the steppers get internal vibrations so they stall, wtf can that be due to ?
[13:11:24] <MarkusBec_away> MarkusBec_away is now known as MarkusBec
[13:11:33] <MrSunshine> it sounds like a bushing that gets tightish so that it gives a squeeking sound :/
[13:12:53] <MrSunshine> gah this sucks, if i wanna upgrade my stepper board this board can take 36V the other they have can only take 32V
[13:12:59] <MrSunshine> and ive got a 36V supply :P
[13:16:43] <anonimasu> hm.. isnt ti resonance that causes that to happen
[13:17:40] <MrSunshine> ti resonance?
[13:19:12] <MrSunshine> hmm, vibrations due to jerking of the motor?
[13:19:53] <MrSunshine> but it sounds like something is very wrong like i got dirt in there or its starting to "sease up" ?
[13:20:04] <MrSunshine> like you get from a computer fan when its giving up
[13:24:38] <MrSunshine> sure if it just stalled .. but the sounds it makes makes me a bit nervouse ive managed to destroy the motors somehow :)
[13:26:41] <MrSunshine> and it stalls out at many places, like at 700 mm/min - 1200mm/min it wants to stall both here and there :/
[13:27:54] <MrSunshine> at 1200 i can make it out to be 32000 steps/s
[13:28:02] <MrSunshine> can that be right ? :)
[13:28:12] <MrSunshine> leadscrew pitch of 2mm
[13:28:22] <alex_joni> MrSunshine: things like this can only be debugged piece-wise
[13:28:27] <alex_joni> take the motor from the machine
[13:28:35] <alex_joni> check how it works at all speed ranges
[13:28:47] <alex_joni> put on the machine, don't connect the coupling, test again
[13:28:55] <alex_joni> move the machine by hand see if you feel rough spots
[13:28:56] <alex_joni> etc
[13:39:53] <MrSunshine> alex_joni, well its when its free it stalls out like that
[13:39:59] <MrSunshine> goes a bit better when its on the machine
[13:41:03] <MrSunshine> are stepper motors lubable in someway or should i stay away from that? :)
[13:49:21] <cradek> what kind of drivers are you using?
[14:02:04] <alex_joni> sounds like midbase resonance to me
[14:05:55] <MrSunshine> Stepper Driver 1.8A 12-36v 4-Axis, TA8435 based
[14:06:38] <MrSunshine> think they have a bit low chopping frequencies or something also, motors scream like hell when idle :)
[14:06:59] <skunkworks_> what kind of microstepping does it have?
[14:08:02] <MrSunshine> 1/8 it looks like
[14:08:16] <MrSunshine> i thought it was 1/16
[14:08:18] <MrSunshine> strange
[14:08:48] <cradek> there are a few modes possible but I'm having trouble understanding the data sheet well enough to say how to select them
[14:09:08] <cradek> "Sinusoidal micro step operation is accomplished only a clock signal inputting by means of built-in hard ware."
[14:09:09] <MrSunshine> on my driver board i just move a couple of switches to select modes
[14:10:15] <cradek> do those control M1,M2 signals?
[14:11:02] <MrSunshine> dont know i havent built the board :)
[14:12:33] <cradek> I'd try M1=high, M2=low for 8 microsteps sinusoidal
[14:12:43] <cradek> it also has straight half stepping
[14:13:02] <MrSunshine> according to datasheet on the driver its off off for 1/8 steps
[14:13:15] <MrSunshine> http://www.brundin.biz/redirect.php?action=url&goto=www.brundin.biz%2Fimages%2Fdatasheets%2F4-axisdriverboardTA.pdf
[14:13:42] <cradek> I disagree
[14:14:18] <cradek> oh your board's datasheet? I was looking at the driver chip's.
[14:15:16] <MrSunshine> cradek, aye my boards datasheet =)
[14:15:18] <cradek> for me, that pdf is blank except for some useless screen shots of some other control software
[14:15:44] <MrSunshine> cradek, at the beginning there is pictures of the board and info about connectors etc for me
[14:16:00] <cradek> ok
[14:16:18] <skunkworks_> I get scolded that I need to download some font. ;)
[14:16:20] <MrSunshine> The resolution setup
[14:16:20] <MrSunshine> S2/S1 ON/ON non resolution ON/OFF 1/2 OFF/ON 1/4 OFF/OFF 1/8
[14:21:00] <MrSunshine> can chopping frequency etc make motors stall out also at strange stepping frequencies? :)
[14:36:24] <Jymmm> ug
[14:36:52] <JT-Work> Jymmm: that monitor is not available and is way too big for my lathe :)
[14:37:27] <Jymmm> swap lcd's
[14:38:13] <JT-Work> it would be a nice one for down in the beer cave
[14:40:44] <Jymmm> there ya go
[14:41:52] <anonimasu> now the question is how do I get the 2.4 pre
[14:42:13] <cradek> you can get it from git, or there are packages
[14:42:26] <JT-Work> cradek: types fast :)
[14:43:18] <anonimasu> hm, where can I find that packages?
[14:43:24] <JT-Work> http://emc2-buildbot.colorado.edu/~buildmaster/
[15:00:24] <anonimasu> thanks
[15:14:53] <anonimasu> now the question is how I get the 7i43 working..
[15:21:02] <anonimasu> where do I put the firmware for the 7i43?
[15:22:27] <SWPadnos> /lib/firmware/hm2/ probably
[15:23:09] <SWPadnos> if you had a previous version of EMC2 installed, there should already be firmware for you though, and maybe /lib/firmware/hm2 is a link to another directory
[15:24:54] <anonimasu> I see the fimrware in the package manager too
[15:25:28] <SWPadnos> you should be able to use the old firmware, I believe. I don't think there are any changes to its functionality
[15:26:16] <anonimasu> ocw said I might need to use the new one to make use of the bitfile he made
[15:26:37] <anonimasu> (if I got him right)
[15:26:43] <SWPadnos> ok, that could be
[15:27:10] <SWPadnos> wait, he made specific firmware for you?
[15:27:33] <SWPadnos> in other words, did he send you a bitfile?
[15:27:37] <anonimasu> he fixed the pin file for the 7i43
[15:27:43] <anonimasu> err 47
[15:27:45] <anonimasu> 7i47
[15:28:40] <pcw_home> You may have to shorten the bitfile name. theres a path length limitation
[15:29:09] <anonimasu> what steps do I have to take to get the card working at all?(first things first)
[15:29:23] <anonimasu> I get some stuff like "fauled to reset fpga"
[15:29:41] <SWPadnos> copy the new firmware into the same directory as the old firmware resides, and change the name of the firmware in your ini/HAL files
[15:29:56] <SWPadnos> oh. then pcw will have to help :)
[15:30:10] <anonimasu> better question is is there docs on what I need to get i tworking
[15:30:28] <anonimasu> do I need aux power for the boards also?
[15:30:43] <pcw_home> Failed to reset FPGA can mean a lot of things, either power supply or EPP communication related
[15:30:50] <SWPadnos> has the 7i43 ever worked on this computer?
[15:32:03] <anonimasu> no it's brand new
[15:32:14] <pcw_home> If this is a motherboard parallel port, you shoudl make sure that ist set to EPP mode in the BIOS
[15:32:24] <anonimasu> let me check
[15:34:28] <anonimasu> epp mode should be what?
[15:34:44] <SWPadnos> EPP
[15:34:46] <anonimasu> 1.7 or 1.9
[15:34:50] <SWPadnos> ah :)
[15:35:46] <anonimasu> found it http://www.linuxcnc.org/docview/html//man/man9/hm2_7i43.9.html
[15:36:05] <pcw_home> 1.9 preferred
[15:39:32] <anonimasu> hm, I have no jumper for usbpwe
[15:39:33] <anonimasu> pwr
[15:39:54] <anonimasu> as it should be
[15:41:36] <anonimasu> will my 7i43 load with the wrong bitfile?
[15:41:42] <anonimasu> to see if my communication works?
[15:42:15] <pcw_home> it will load any 7i43 200K bitfile
[15:43:05] <anonimasu> so, I should be able to just connect it to the port and try loading it with a file?
[15:44:17] <pcw_home> You should be able to just connect it, supply 5V power, and run the demo config
[15:44:36] <anonimasu> ah.. so I need aux 5v power too.. that clears it up
[15:44:55] <alex_joni> well.. the parport doesn't have 5V
[15:45:07] <pcw_home> The 7i43 needs 5V power...
[15:45:10] <alex_joni> that's why it's best to hook up the usb cable too (simplest solution)
[15:45:32] <anonimasu> but I were stupid and bought without usb...
[15:45:39] <alex_joni> pcw_home: yeah, I know.. parport having 5V on it would have saved a LOOOT of issues in the last few years
[15:45:47] <alex_joni> anonimasu: then you need to connect 5V to it somehow
[15:45:55] <alex_joni> old usb mouse cable works too ;)
[15:46:10] <alex_joni> just cut it, use the 5V wires, connect to 5V terminals on the 7i43
[15:46:16] <PCW_> PCW_ is now known as PCW
[15:46:55] <anonimasu> I'll wire up a 5v adapter :) later for now I need to get the powersupply
[15:46:56] <anonimasu> brb
[15:48:36] <anonimasu> or take a usb cable and steal the 5v..
[15:49:00] <elmo40> or take some from your power supply!. 7805 will do the trick.
[15:55:24] <pcw_home> Beware of leakage from separate power supplies. make sure the PC ground and power supply ground are connected together
[15:55:26] <pcw_home> somewhere other tnan just the parallel cable
[15:55:37] <pcw_home> (than)
[15:58:40] <elmo40> i wouldnt connect any parallel ground with powersupply ground. the signal should never interact with power supply.
[16:01:05] <pcw_home> The problem is if you have a floating supply and hot-plug the parallel connection you may damage the PC or 7I43
[16:01:07] <pcw_home> the power supply must have a common ground with the PC (this can be through the parallel cable, but then hot plugging can cause damage)
[16:01:46] <pcw_home> Using the PCs 5V is probably safest
[16:02:17] <elmo40> what is the need to hot plug?
[16:02:43] <pcw_home> No need but people seem to do it...
[16:02:49] <elmo40> :P
[16:04:14] <skunkworks> * skunkworks hugs his pci card
[16:04:26] <skunkworks> (s)
[16:06:15] <skunkworks> pcw_home: http://electronicsam.com/images/KandT/conversion/newelecin.JPG
[16:07:24] <elmo40> large board.
[16:07:39] <elmo40> where does it plug into? pci slot?
[16:07:55] <pcw_home> I've learned this from using cell phone chargers as 5V aux supplies, 5V 1A ones are common but
[16:07:57] <pcw_home> the outputs float at about 60=80VAC since their RFI filters return to the power line.
[16:07:58] <pcw_home> They work fine for running things like a 7I43, but dont hot plug the parallel connection
[16:08:00] <pcw_home> because if the first pin that happens to connect is a signal instead of ground pin, you lose....
[16:09:04] <elmo40> skunkworks: what is that board for?
[16:09:19] <pcw_home> skunkworks: you've got a good assortment of OPTO 22 racks...
[16:09:27] <skunkworks> ebay is awesome ;)
[16:09:33] <elmo40> that it is
[16:10:07] <skunkworks> pcw_home: http://electronicsam.com/images/KandT/conversion/16io.JPG
[16:10:18] <skunkworks> I don't know if you saw that.. worked great
[16:10:26] <anonimasu> hm so what about using a usb cable.. and just stealing the power... lines
[16:11:01] <skunkworks> elmo40: this build is going to use 2 5i20s
[16:11:13] <elmo40> nice.
[16:11:14] <skunkworks> mesa pci 72 i/o boards
[16:13:46] <pcw_home> anonimasu: thats a good solution. If the 7I43 has the USB stuff, its best to cut the data wires in the cable
[16:13:53] <elmo40> skunkworks: get that motor all cleaned up? i only see 'before' pictures
[16:14:06] <anonimasu> well, for now my lab supply will work
[16:15:43] <skunkworks> elmo40: I don't think I have a finished picture http://electronicsam.com/images/KandT/conversion/servo/commutator.JPG
[16:16:16] <pcw_home> ( the 7I43 will use about 150 mA of your 450 mA USB power leaving ~300 mA for your
[16:16:18] <pcw_home> daughtercards so don't try to power up any ancient incandescent lamp encoders or such)
[16:23:24] <anonimasu> it works kindof but emc dosent start
[16:23:26] <anonimasu> err load..
[16:23:28] <anonimasu> brb
[16:25:04] <PCW_> PCW_ is now known as PCW
[16:25:07] <skunkworks> anonimasu: make sure you have the firmware package.
[16:37:16] <MrSunshine> hmm got the motors to run a little more nicley tweaking the step time etc values
[16:37:27] <MrSunshine> but still wants to stall out over about 600 mm/min
[16:37:35] <PCW_> PCW_ is now known as PCW
[16:37:51] <MrSunshine> hell they even stall out without load on them at higher speeds, if im not holding the motor firmly so i guess its a resonance issue
[16:46:31] <elmo40> there enough current pushing through them?

[17:04:17] <SEALIVE> iv been out for 5 hours watching the second day of the new house bilding around the corner
[17:04:47] <SEALIVE> it now looks out of nothing from saturday,like the house war's ever there
[17:06:30] <SEALIVE> the work at thew house startet yesterday 5:30 local
[17:07:21] <SEALIVE> the house wars bult by 14:45 with breaking the glas of the roof

[17:13:16] <SEALIVE> but it worked out at xbuntu 500Mhz 128Mb 5GB
[17:29:35] <JT-Work> oh lovely OneCNC just ruined a part I've been working on since Friday :/
[17:34:47] <pcw_home> JT-Work Did you help it or did it ruin it all by itself?
[17:35:23] <skunkworks> when is that getting converted to emc/
[17:35:24] <skunkworks> ?
[17:35:27] <JT-Work> I didn't double check what it picked with my print when I picked a pocket depth
[17:35:56] <JT-Work> it picked some hidden feature below what I thought I had picked
[17:36:07] <JT-Work> so the pocket was too deep
[17:36:18] <pcw_home> Oops...
[17:36:31] <JT-Work> yea
[17:37:02] <JT-Work> at least no blood letting occurred during the process
[17:38:54] <pcw_home> I'll bet a few bad words were issued...
[17:39:47] <JT-Work> no, I refrained from that as it was as much my fault for not checking as I know OneCNC is flaky like that
[17:40:15] <pcw_home> Wheres the "Do What I Mean: interface when you need it
[17:41:02] <JT-Work> yea, they don't have one and I'm spoiled by Solidworks 2010 as it almost has that LOL
[17:43:25] <JT-Work> and that part has a 0.125" hole through 2.5" of 1018 and needs to be straight :) and that is fun to do
[17:44:33] <GonMD> ouch
[17:44:46] <GonMD> if you can avoid it, never work with 17-4 PH
[17:44:54] <pcw_home> thats long skinny hole to keep straight
[17:45:14] <skunkworks> gun bore!
[17:45:34] <JT-Work> yea, a parabolic drill helps a lot
[17:45:56] <pcw_home> Pretty small gun bore
[17:47:09] <pcw_home> Though I have shot single shotgun pellets with single grain of rifle power in my misspent youth
[17:47:21] <pcw_home> (powder)
[17:49:12] <JT-Work> I've done a few things in my youth with home made black powder when you could still buy the supplies at the drug store LOL
[17:51:36] <JT-Work> a nutty friend wants me to ream out his black powder rifle so he can use it as a black powder shotgun

[17:53:42] <archivist> I learnt how the charge shape mixed with the strength of the enclosure changed a mild burn to a full explosion :)
[17:54:00] <pcw_home> When I was 12 or so I could buy black power at the local gun shop for like $2.00 a pound

[17:57:26] <pcw_home> Well now you know what not to do...
[17:59:11] <pcw_home> well back to debugging an fighting with Xilinx tools...
[17:59:12] <pcw_home> bbl
[18:00:23] <piasdom> JT-work; do you have a 1/8" or 3/32" endmill to start the cut...need to go about a 1/4" deep
[18:01:33] <frallzor> * frallzor is sweaty
[18:06:25] <JT-Work> piasdom: I use a spotting bit to start the hole
[18:06:35] <JT-Work> 120 degree
[18:11:41] <elmo40> JT-Work: what is OneCNC?
[18:12:34] <SWPadnos> http://www.onecnc.com/
[18:14:40] <JT-Work> elmo40: it is click, click, click, click, click, click, click, click, click, click, click, click, click, click, click with your mouse
[18:15:39] <skunkworks> heh - shows how much I know - I thought onecnc was a machine control.

[18:19:03] <anonimasu> time to test the second mesa board :]
[18:20:50] <skunkworks> anonimasu: what was the issue with emc not loading?
[18:21:10] <anonimasu> it mentioned old firmware
[18:21:13] <anonimasu> and it didnt start
[18:24:12] <JT-Work> the good thing is the quad rings for my collet closer and turret came in along with other needed hardware for the Hardinge
[18:24:56] <MattyMatt> I like the ATC in the OneCNC vid. it puts them away in the cupboard :)
[18:26:04] <frallzor> wooow the mill is starting to look like a mill now
[18:26:25] <JT-Work> frallzor: got any photos?
[18:26:35] <frallzor> will be taking some soon =)
[18:26:53] <frallzor> did a manual test of all axis too, works like finger up an eskimos ass
[18:27:06] <frallzor> meaning bloody great =)
[18:27:42] <MattyMatt> I've eliminated the flex in my head. I added a 3rd slide at right angles like I was supposed to in the original design
[18:27:44] <JT-Work> OK, I never did that and I was born on King Salmon Island
[18:27:49] <JT-Work> or never seen that
[18:28:02] <archivist> how do you know about the efficacy of an eskimos arse
[18:28:04] <frallzor> oh im too bored, picture time!
[18:28:25] <piasdom> Jt-Work; it needs to go deeper than a c-drill, it will help start it straight. even a c-drill can walk when the depth is deep 2 1/2" is a LONG destant for an 1/8" drill
[18:30:01] <JT-Work> piasdom: what is a c-drill?
[18:30:02] <piasdom> Jt-Work; this always works for my....and the drill needs to be equal on both sieds of the taper
[18:30:36] <piasdom> centerdrill....is that a spotting bit ?
[18:31:20] <JT-Work> no a center drill is not a spotting bit but sometimes confused for one
[18:31:40] <piasdom> never heard of it...thought it was thge same
[18:31:48] <piasdom> *the
[18:32:03] <JT-Work> totally different function for each
[18:32:27] <SEALIVE> witch is the best to use for drilliing with a mill tool
[18:32:33] <piasdom> do you sharpen your own drill bits ?
[18:32:47] <JT-Work> http://www.lakeshorecarbide.com/singleendcarbidespotdrills.aspx
[18:32:50] <JT-Work> no
[18:33:19] <JT-Work> the 120° are for 118° and 135° bits
[18:33:39] <JT-Work> SEALIVE: between what choices
[18:33:45] <piasdom> i can those drill bit
[18:34:39] <piasdom> but even a c-drill will walk if your drill bit is sharpened unevenly
[18:34:47] <piasdom> can = call
[18:35:13] <JT-Work> I never use a center drill for spotting
[18:35:46] <SEALIVE> i normaly use a high speed VHM drill to cut of the center 1nch deep for milling 15mm holes with a 14mm 7flute tool co8
[18:35:51] <JT-Work> If I really want something in the lathe centered I use a spotting bit then a center drill for my live center
[18:35:56] <piasdom> all i ever use....one touch is all i need
[18:36:48] <SEALIVE> i go thru in one shot at 8000RPM and 345mm/min
[18:37:05] <SEALIVE> 16Bar of cooliing presure
[18:37:16] <SEALIVE> at 1.2379
[18:37:25] <piasdom> how big is the spotting bit you're using ?
[18:37:34] <SEALIVE> 8mm
[18:37:34] <JT-Work> 1/8"
[18:37:55] <piasdom> how big is the flat tip
[18:38:17] <piasdom> if there is one
[18:38:18] <frallzor> http://pici.se/p/large/IFcydmXZQ/ http://pici.se/?p_large/iPdPEjsDK tadaaaaa
[18:39:20] <JT-Work> I'd have to get my jewelers loop out to see LOL
[18:39:27] <piasdom> hhahahhaha
[18:39:51] <JT-Work> frallzor: nice :)
[18:40:01] <frallzor> made a vid too with me moving it :P
[18:40:03] <JT-Work> but you need more light
[18:40:09] <piasdom> if it is always walking....the bit may be sharpened unevenly or too old :)
[18:40:15] <frallzor> cant do better atm :P getting better light out there
[18:40:39] <JT-Work> piasdom: I only use fresh sharp new spotting bits :)
[18:40:49] <piasdom> get you loop out and look at the tip
[18:42:03] <piasdom> JT-Work; try going deeper with the spot bit then
[18:42:42] <JT-Work> why?
[18:43:52] <piasdom> the drill bit need a better start the a spot...i usually go deep enough so the taper of the drill bit is in the hole before it starts cutting
[18:43:58] <JT-Work> looks to be 0.020 wide flat
[18:44:20] <piasdom> and the tip of the drill ?
[18:44:23] <JT-Work> I don't have any trouble drilling the hole :?
[18:44:30] <SEALIVE> if u use VHM price is not more then 1/3+ of HSSTIAN vyou can go thru
[18:44:55] <piasdom> i thought you were having trouble getting it to go straight
[18:45:26] <piasdom> that's the only reason i started this :)
[18:45:33] <JT-Work> my trouble was OneCNC used an incorrect pocket depth and ruined my part which had a long skinny hole as one of the features
[18:45:52] <piasdom> cool...
[18:46:21] <JT-Work> I can keep the hole location within 0.001 from start to finish :) after all the practice I've had making this part
[18:46:31] <SEALIVE> did the programm or the mashine fail
[18:47:29] <piasdom> then i misunderstood the problem...
[18:49:47] <anonimasu> the mesa cards of mine works
[18:53:45] <SEALIVE> coudt someone of you please check if youtube.com is offline?
[18:54:53] <PCW> Maybe a little tricky to trace from the .PIN file to the 7I47 I/O sine the pin file only gives 50 pin cable pin-out
[18:55:02] <PCW> (since)
[18:55:05] <SEALIVE> ok wars down for some minutes now up and running from germany !
[18:55:57] <anonimasu> so I need to guess what the I/O is on the 7i47
[18:57:15] <PCW> Well the 7I47 manual in conjunction with the .PIN file should be enough info
[18:57:57] <SWPadnos> dmesg will also help, since hostmot2 prints the pinout there
[18:58:14] <anonimasu> ah yeah
[18:58:23] <anonimasu> wtf..
[18:58:29] <PCW> It would be nice if the pin file generator had a daughterboard option
[18:58:33] <anonimasu> can not find -sec emc .var nml
[18:59:52] <anonimasu> linux parport does not support mode 4
[18:59:54] <anonimasu> :S
[19:01:14] <SWPadnos> remove the NMLFILE from your ini
[19:01:30] <JT-Work> piasdom: mostly it was PEBKAC
[19:01:40] <anonimasu> hm, it's the default install of the new emc2
[19:01:43] <JT-Work> alex_joni: taught me that
[19:01:52] <SWPadnos> hmm
[19:07:20] <MattyMatt> argh my new stiffened Z, the motor won't raise it anymore
[19:07:35] <MattyMatt> too heavy
[19:08:06] <MattyMatt> I only added about a pound
[19:08:22] <JT-Work> straw that broke the camels back I guess
[19:09:16] <anonimasu> I get no such device about the 7i43
[19:10:29] <MattyMatt> time to buy bigger motors. concept is proved, machine is now worth spending on
[19:10:57] <anonimasu> it seems missing :S
[19:12:07] <PCW> anonimasu: did you get to the point that the demo config loaded the firmware?
[19:13:52] <MattyMatt> * MattyMatt puts heavy motor on Z, and now X won't move
[19:16:36] <JT-Work> PCW: I did get that 5i20 off to you in the mail yesterday
[19:21:08] <SEALIVE> ok By till tomorrow
[19:22:25] <DaViruz> http://daviruz.meeep.net/DSC_0069.jpg
[19:22:29] <DaViruz> new bench for the bench mill!
[19:22:42] <frallzor> swedes rock!
[19:22:59] <DaViruz> hopefully this will bring order to vises, tools and all the other crap erlated to milling that's all over the place now..
[19:23:58] <JT-Work> DaViruz: nice
[19:26:40] <DaViruz> thanks, i'm really satisfied with it :)
[19:27:06] <PCW> JT-Work: Thanks! last one with this trouble was in Australia and they just re-flashed it rather than sending it back so I never could figure what happened to it
[19:27:59] <DaViruz> apart from the 5mm steel sheet top that could have been a little larger, but that was the largest piece i could find :/
[19:29:08] <JT-Work> I never could get my floppy drive to work on that computer and was so busy with the Hardinge it was the best way :)
[19:41:52] <PCW> Thanks again and sorry for the trouble, will send replacement asap
[19:43:23] <JT-Work> ok, no problem... how did the goat roping circus go Sunday?
[19:45:20] <anonimasu> PCW: yeah with the old emc
[19:47:35] <anonimasu> it looks like this install dosent have the modules includede
[19:47:37] <anonimasu> included
[19:47:40] <MattyMatt> I suppose I should up the voltage before I give up on these motors. 12V atm
[19:48:06] <andypugh> 12V is unusually low.
[19:48:21] <andypugh> But it depends on whether you lack speed or torque.
[19:48:29] <MattyMatt> torque
[19:48:43] <MattyMatt> Z won't raise anymore
[19:48:48] <andypugh> More volts won't give you any more torque at low speed, just higher torque at high speed.
[19:49:14] <andypugh> Will it rise at a lower speed?
[19:49:14] <MattyMatt> plan B, turn up the current
[19:49:41] <MattyMatt> no even at low speed it won't lift
[19:49:45] <andypugh> Do you plan on selling the motors?
[19:50:08] <MattyMatt> no, they cost me 10q for 4
[19:50:24] <andypugh> So turn up the current until they either work, or smoke comes out.
[19:50:59] <MattyMatt> double shafted, thel make nice knees or glutei maximus for a biped
[19:51:46] <MattyMatt> asimo still sell for $.25m, afaiaa :)
[19:52:20] <andypugh> Now, it it glutei maximus or gluteus maximi? Your way seems right, but looks wrong.
[19:53:21] <PCW> anonimasu whats missing?
[19:53:25] <MattyMatt> it could be glutei maximi, I forget if the adj follows the noun form
[19:53:33] <andypugh> The workshop beckons.
[19:53:58] <MattyMatt> long time, no latin prep :) I got caned for not doing it once. ah, happy schooldays
[19:54:21] <MattyMatt> another time I was caned for not attending chapel wearing my cap
[19:54:39] <andypugh> http://www.merriam-webster.com/dictionary/gluteus+maximus
[19:54:52] <andypugh> "plural glutei maximi"
[19:55:09] <MattyMatt> cool
[19:55:18] <MattyMatt> no caning for me tomorrow
[19:55:18] <andypugh> Were you caned for rubbing linseed oil into the school cormorant?
[19:55:59] <MattyMatt> I got out of that school by stowing away on a chinese cargo boat
[19:57:29] <MattyMatt> for an hour, but the lifeboats had padlocked lids and I saw a chef with a cleaver, so I got off and phoned home to negotiate
[19:57:33] <andypugh> "In memory of all those boys from the school who died to keep China British?"
[19:58:29] <MattyMatt> I shoulda stayed on the boat. Hong Kong woulda been cool
[19:59:46] <andypugh> Ah, you mean that was actually true? I thought it was in reference to: http://www.youtube.com/watch?v=InqBDv_9ar0
[20:01:28] <MattyMatt> it was more like http://www.youtube.com/watch?v=GJ1LG08ssaM
[20:02:34] <alex_joni> here's a nice machine for auction http://www.surplex.com/en/machines/marketplace,7,axa-vhc-50-travelling-column-machining-center-87652.html
[20:07:09] <andypugh> Hmm, I doubt that would fit in my house, in fact I think my house would fit in it.
[20:16:24] <MattyMatt> "I was 17 miles from Greybridge before I was caught by the school leopard." :)
[20:19:54] <MattyMatt> 37kW spindle?
[20:21:02] <anonimasu> hm2_7i34.ko missing
[20:21:19] <anonimasu> -1 no such device
[20:21:26] <MattyMatt> you'd need more than 3 houses. they won't supply more than 12kW to one
[20:22:33] <anonimasu> linux parport does not support mode 4
[20:22:38] <anonimasu> PCW: you there?
[20:23:36] <PCW> Linux really should not have any access to the port anyway so thats OK but the missing hm2_7i43 is fatal
[20:24:01] <anonimasu> shouldnt that be included with the emc install?
[20:24:17] <PCW> Maybe you could ask on the developers list why its missing...
[20:24:31] <anonimasu> it werent missing before this afternoon
[20:24:51] <skunkworks> anonimasu: I 'think' the firmwares are a separate package...
[20:24:59] <anonimasu> but I installed that already
[20:39:53] <MattyMatt> sweet. Z moves nicely with 1.75A through 1A motor
[20:40:39] <skunkworks> scary
[20:41:14] <Jymmm> Motors roasting over an open fire...
[20:41:55] <MattyMatt> it's an 8 wire motor, so the coils are actually safe for 2A in parallel aren't they?
[20:43:51] <MattyMatt> anyway, it's at the top of the machine. the flames won't play against the woodwork
[20:45:29] <Jymmm> The molten metal might =)
[20:45:30] <MattyMatt> momma, check the fine print on the house insurance
[20:50:34] <MattyMatt> I put it in 1/2 step, so 1.75A is peak
[20:59:00] <JT-Hardinge> anonimasu: you might have to use the package manager to install the bit files
[20:59:06] <anonimasu> I did
[21:04:21] <anonimasu> wtf....
[21:05:27] <JT-Hardinge> just guessing
[21:05:36] <anonimasu> it seems like I have a parport loaded
[21:07:02] <anonimasu> error inserting /usr/realtime-2.6.24-16-rtai/modules/emc2/hm2_7i43.ko -1 no such device
[21:07:42] <JT-Hardinge> you running RIP or installed?
[21:07:52] <anonimasu> RIP?
[21:08:10] <anonimasu> it's a clean emc2 install from the cd
[21:08:11] <Jymmm> andypugh: Rest In Piece(s)
[21:08:21] <anonimasu> then upgraded to the pre version
[21:09:56] <anonimasu> and it works with emc2(not the 2.4 pre)
[21:13:47] <anonimasu> http://www.io23.net/ul/files/error.txt
[21:19:49] <JT-Hardinge> Run In Place
[21:20:04] <JT-Hardinge> * JT-Hardinge smacks Jymmm on the back of his head
[21:20:44] <anonimasu> hm.. nothing like that
[21:20:52] <anonimasu> the 2.4 pre seems too broken to run at all right now
[21:21:02] <MattyMatt> 11cm between tool tip and bottom of drill vice jaws when raised to top. So I've got 4" travel effective
[21:21:12] <MattyMatt> not bad for a router
[21:23:45] <Jymmm> JT-Hardinge: I siad what i mean, and i mean what I said!
[21:24:04] <Valen> MattyMatt if your over running it like that I'd suggest doing a bunch of rapid short Z's and make sure it doesn't over heat
[21:24:25] <anonimasu> machine a heatsink for yourself
[21:24:51] <MattyMatt> the motor casing is barely warm
[21:26:05] <Valen> sounds good then just make sure it doesn't get over ~60-80C
[21:26:07] <MattyMatt> temp sensors inside would be nice, between each pair of coils
[21:26:15] <Valen> alot of magnets get screwed at about that temp
[21:26:39] <MattyMatt> I think they are soft iron, not hybrids
[21:26:43] <Valen> hmm I've got 3Gb of download left and a few hours to use it
[21:26:47] <Valen> any suggestions?
[21:26:47] <MattyMatt> slo-syn
[21:27:04] <MattyMatt> they are the size of modern 2A motors, anyway
[21:27:08] <Valen> if they are steppers they will have magnets,
[21:27:16] <MattyMatt> certainly no Nb magnets
[21:27:35] <Valen> especially at that low current level
[21:28:09] <Valen> ey theres a thought, if you wanted more torque out of a stepper system, whack NIB magnets into it, it might chop down the top speed some but still, pretty cheap
[21:28:22] <SWPadnos> Valen, download an Ubuntu 10.04 ISO
[21:28:37] <SWPadnos> beta 1 is out
[21:28:55] <Valen> lol thats probably unmetered for me
[21:29:20] <Valen> my ISP has its own sourceforge mirror and most of the linuxes
[21:29:30] <Valen> and all downloads from there aren't counted
[21:29:35] <SWPadnos> oh. well in that case I don't know :)
[21:31:18] <Valen> lol yep there they are
[21:31:34] <Valen> also means all my linux needs are taken care of at line speeds ;->
[21:31:37] <MattyMatt> if my Z motor hasn't melted in a week or two, I'll turn up the current on the table too
[21:31:39] <Valen> I really like them as an ISP ;->
[21:32:15] <Valen> SWPadnos anything good in 10.04?
[21:32:45] <SWPadnos> LTS
[21:33:07] <SWPadnos> later Gnome and some other stuff of course, faster bootup, later kernel ...
[21:33:15] <Valen> yeah but thats not "cool" or nifty like upstart and ext4
[21:33:23] <Valen> faster boot ay
[21:33:37] <Valen> mine already starts faster than the bios
[21:33:45] <Valen> ie bios time is > than boot
[21:34:04] <Valen> though i am running off a SSD with a quad core
[21:34:30] <MattyMatt> that sounds like you need a bios upgrade
[21:34:32] <mikegg> I just put a SSD in my Mac
[21:34:36] <SWPadnos> how recent is your motherboard?
[21:34:40] <mikegg> man those things are sweet :)
[21:34:50] <Valen> under a year
[21:35:11] <SWPadnos> does it have SATA3 (SATA 6 Gb/s)
[21:35:13] <Valen> this bios seems to take a while to detect IDE stuff, ~8-10 seconds or so
[21:35:13] <SWPadnos> ?
[21:35:18] <Valen> no only sata 2
[21:35:21] <Jymmm> Valen: you're an aussie?
[21:35:21] <Valen> I think
[21:35:21] <SWPadnos> bummer
[21:35:24] <Valen> yeah
[21:35:36] <Jymmm> Valen: ah
[21:35:50] <Valen> the SSD maxes out at 180mbyte/sec anyway so sata 2 is enough
[21:35:50] <SWPadnos> there's a new SSD that's blazingly fast - something like 360 MB/sec random reads, and writes not too far behind
[21:36:07] <MattyMatt> http://www.coreboot.org/Welcome_to_coreboot
[21:36:10] <SWPadnos> it can probably attach to a SATA II port, and would be limited by that channel
[21:36:18] <mikegg> I want one of the ones that drops in a PCI Express slot
[21:36:24] <Valen> probably a bazillion dollars though
[21:36:36] <SWPadnos> the PCIe ones are waaaaay too expensive
[21:36:42] <SWPadnos> like $1000 for 250GB
[21:36:42] <Jymmm> and as reliable as M4 to very have viruses
[21:36:44] <Jymmm> M$
[21:36:51] <Valen> yeah I'd do that but 99% it wont support my mbo
[21:36:52] <Jymmm> never
[21:36:54] <mikegg> yeah, like could be driving a new car instead expensive
[21:37:10] <SWPadnos> the SATA3 ones are also expensive, like $450/128GB or $750/256GB
[21:37:15] <Valen> actually the pci-e ones are a reasonoble price
[21:37:23] <Valen> compared to sata of the same size
[21:37:36] <Valen> thats still on par I think SWPadnos
[21:37:41] <SWPadnos> there's a 1TB PCIe "drive" that's $3800, but has ~800MB/sec reads
[21:37:52] <Valen> Jymmm: whats wrong with being an aussie?
[21:38:00] <Valen> that would be nice
[21:38:13] <Valen> 2/3rds of what I paid for my shiny red car but still
[21:38:22] <Jymmm> Valen: too many thngs to list =) lol
[21:38:25] <SWPadnos> the SATA3 drive is fast. "boots Windows 7 in under 10 seconds" :)
[21:38:37] <Jymmm> Valen: Nah, was just making sure I got your ISP correctly
[21:38:45] <Valen> internode
[21:38:55] <Jymmm> Valen: Yeah, I know.
[21:40:02] <Valen> thats odd, I figured freenode would hide the ip address
[21:40:23] <Jymmm> Valen: It would, if you had a cloak AND logged in
[21:40:46] <Valen> I would also need to care
[21:40:51] <Valen> ;->
[21:41:08] <Valen> most irc networks mask it by default is all
[21:41:34] <Jymmm> no, they don't.
[21:41:40] <Valen> at the moment I know I'm safe because as soon as somebody tries to hack me my modem will overheat and die making me safe
[21:41:43] <Jymmm> or else DCC wouldn't work.
[21:42:20] <Jymmm> security thru thermal breakdown.... that's a new one.
[21:42:28] <Valen> my understanding was the DCC request went through the normal IRC network and its only if you responded it gave out the address?
[21:42:57] <Valen> my mbo isn't on the coreboot sire
[21:42:58] <Valen> site
[21:47:02] <motioncontrol> good evening at all. please have a problem with call file fuction type o<myfile> call. some people can help me ?
[21:56:20] <andypugh> motioncontrol: Have you seen http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?SubProgramFiles
[21:56:27] <JT-Hardinge> yea what you got?
[21:57:13] <JT-Hardinge> http://www.linuxcnc.org/docview/html//gcode_main.html#r3_7
[21:57:33] <motioncontrol> andypugh, thanks i read it. i have execute some prove , but not fuction.i read doc thanks
[21:58:10] <motioncontrol> JT-Hardinge, yes i have prove your doc , but not is ok
[21:58:18] <andypugh> The main thing seems to be that the called file needs to contain a sub with the same name or number as the filename
[21:58:38] <MrSunshine> elmo40, hmm, dont know realy the motors wants 2A and the driver gives max 1.8A if im not mistaking, might be a problem ? :)
[21:58:39] <JT-Hardinge> motioncontrol: what error do you have?
[21:58:47] <Valen> I wonder how coreboot would help latency on one of those atom boards perhaps
[21:59:26] <motioncontrol> JT-Hardinge, not execution the sub , the program stop at m2. i append the image one moment
[22:00:07] <JT-Hardinge> ok
[22:00:14] <MrSunshine> i want a 4A driver so i can parallel connect the motors ... sigh :/
[22:01:20] <Valen> solder some more chips on she'll be right
[22:02:09] <MrSunshine> im starting to think gecko soon
[22:02:16] <MrSunshine> but they are quite expensive
[22:02:45] <motioncontrol> this link for my example :http://imagebin.ca/view/XryBUnI.html
[22:03:01] <motioncontrol> prova1 is the principal program
[22:03:13] <mikegg> does anyone run servo's and steppers in the same setup?
[22:03:21] <Valen> I'm hoping to mikegg
[22:03:32] <mikegg> X-Y servos and Z stepper for example
[22:03:36] <mikegg> cool
[22:03:43] <mikegg> Nema 23?
[22:03:48] <Valen> we have xyz servo and making A a "stepper"
[22:03:52] <Valen> umm not quite ;->
[22:03:53] <mikegg> ok
[22:04:14] <Valen> http://www.youtube.com/watch?v=g2N910jNOnE
[22:04:20] <MrSunshine> ough would need 81V to drive the motor fully at 6.4mH windings :/
[22:04:25] <MrSunshine> according to gecko
[22:04:56] <Valen> its actually a servo motor but using it as a rotary I'm thinking feeding it as a stepper (the controller can handle that as an input) is probably easier
[22:05:36] <motioncontrol> JT-Hardinge, this is the link http://imagebin.ca/view/XryBUnI.html
[22:05:48] <JT-Hardinge> motioncontrol: looks like some syntax errors
[22:06:22] <mikegg> neato
[22:06:33] <motioncontrol> JT-Hardinge, the syntax error why ?
[22:06:38] <JT-Hardinge> proval not proval.ngc
[22:07:02] <motioncontrol> JT-Hardinge, i prove
[22:08:07] <JT-Hardinge> o<proval> call
[22:09:14] <motioncontrol> i have correct, but not read the sub.
[22:09:34] <motioncontrol> i have correct the sub :o<prova1> sub
[22:09:35] <motioncontrol> g0 x0 y0 z5
[22:09:35] <motioncontrol> o<prova1> endsub
[22:09:35] <motioncontrol> m2
[22:10:05] <motioncontrol> the axis not go at g0 x0 y0 z5
[22:11:59] <motioncontrol> JT-Hardinge, have some thing for this problem ?
[22:16:39] <JT-Hardinge> ok I'm back and hands are clean so I can type
[22:17:07] <JT-Hardinge> are you calling a separate file or a sub in the same file
[22:17:44] <motioncontrol> JT-Hardinge, i call a separate file subprogram not subroutine
[22:18:06] <pfred1> Poll: What is everyone's favorite DVD writable media?
[22:18:53] <JT-Hardinge> your subprogram file is prova1.ngc?
[22:19:50] <JT-Hardinge> pfred1: the closest one to my hand when I need one
[22:20:07] <pfred1> JT-Hardinge so low price gets it then?
[22:20:41] <JT-Hardinge> I don't buy them much so the last pack of 50 is still around
[22:20:59] <motioncontrol> yes i have i main progam prova.ngc, and a subprogram prova1.ngc
[22:21:29] <JT-Hardinge> subprogram line one should be :
[22:21:41] <JT-Hardinge> o<prova1> sub
[22:21:46] <JT-Hardinge> same for endsub
[22:23:30] <JT-Hardinge> like manual shows almost clear :/
[22:23:59] <JT-Hardinge> Sweet! turret moves nice and smart and the air compressor has not kicked on yet
[22:24:09] <JT-Hardinge> so no leaks in that part :)
[22:26:41] <motioncontrol> JT-Hardinge, ok thanks now is ok, have syntax error. more thanks
[22:26:54] <JT-Hardinge> I have so many new parts I don't know which end to work on :)
[22:27:00] <JT-Hardinge> motioncontrol: great!
[22:27:36] <JT-Hardinge> Cocoa has been waiting to take me for a walk in the woods...
[22:27:56] <skunkworks> hooker?
[22:28:33] <pfred1> skunkworks sounds like a rough sex in the park episode to me!
[22:29:05] <MrSunshine> are the gecko drives worth the money? :)
[22:29:16] <pfred1> MrSunshine why whats cheaper?
[22:29:28] <MrSunshine> pfred1, stupid drivers that i bought before :P
[22:29:37] <MrSunshine> i get 4 axis for the price of 1 axis gecko :)
[22:29:47] <pfred1> MrSunshine I saw an ad the otehr day for a gecko 3 drive system that you plugged your cable directly into
[22:29:51] <MrSunshine> but they are 1.8A 36V compared to 7A 80V :P
[22:30:17] <pfred1> maybe it was 4 axis I don't remember 504 maybe?
[22:30:31] <MrSunshine> i figured i might buy myself some geckos when i get money
[22:30:36] <pfred1> mariss seems to make some bad assed drives
[22:30:44] <MrSunshine> will set me back like half the price ive payed so far for the whole mill but hell :)
[22:31:13] <pfred1> MrSunshine what kind of lead screws do you have?
[22:31:18] <MrSunshine> i still have the driver that i bought before, can buy some smaller motors for it and build myself a pcb router/driller :)
[22:31:27] <MrSunshine> pfred1, acme or whatever they are called, trapetzoids
[22:31:58] <pfred1> yeah lots seem to skimp on the leads ball screws are 90% efficient as opposed to 40% of acme
[22:32:15] <pfred1> so you'd more than double your performance just dropping new leads in
[22:33:05] <MrSunshine> pfred1, its the default on the mill its a sieg X1 mill im converting :)
[22:33:16] <MattyMatt> only coreboot mobo I've got is a dead Thinkpad T23
[22:33:21] <pfred1> yeah it is common to change over to ball screw on mills
[22:34:01] <MrSunshine> pfred1, i will as soon as i can get it all running as im even having problems running the motors at high speeds without them mounted on the mill i figure something is wrong on the way to the motor :)
[22:34:05] <pfred1> any good commercial CNC conversion changes out the leads
[22:34:15] <MrSunshine> like that i have to run the motors in bipolar serial connection insted of parallel
[22:34:37] <MrSunshine> pfred1, commercial ? its not like im going to sell them :P
[22:34:47] <pfred1> best performance is parallel but your drivers can't handle that right?
[22:35:03] <pfred1> MrSunshine you can still compare what yo udo to what professionals do
[22:35:15] <MrSunshine> pfred1, 1.8A max, motors are rated 2A 4V in serial mode
[22:35:52] <pfred1> and you say unloaded they don't run right?
[22:35:58] <MrSunshine> aye
[22:36:10] <MrSunshine> LOADS of vibrations so they stall out themselfs
[22:36:20] <MrSunshine> unless i hold them realy firmly then they can run at higher speeds
[22:36:26] <pfred1> I had that problem myself until I optically isolated my control signals
[22:36:40] <MrSunshine> pfred1, they are opto isolated on the driver board
[22:36:45] <pfred1> ok
[22:36:46] <anonimasu> 5/n
[22:36:59] <pfred1> but they run OK loaded?
[22:37:34] <MrSunshine> pfred1, run better loaded then unloaded just holding them loosly
[22:38:04] <pfred1> yeah running right they should run fine free
[22:38:10] <PCW_> PCW_ is now known as PCW
[22:38:21] <MrSunshine> pfred1, yeah i figured they should =)
[22:38:32] <MattyMatt> could one coil inverted cause that?
[22:38:36] <pfred1> have you checked their current draw?
[22:39:21] <pfred1> MrSunshine yeah like MattyMatt said are you sure you have the motors phased properly?
[22:39:58] <MrSunshine> pfred1, well connected them according to the place i bought them, as they specify the cables and what winding they should go to
[22:40:06] <MrSunshine> so colors goes to the right holes in the driver
[22:40:21] <MrSunshine> pfred1, nop, how can i do that reliably ? :)
[22:40:42] <pfred1> just put an ammeter in line with the driver power
[22:41:04] <pfred1> and test it free and loaded and see what it does
[22:41:09] <pfred1> loaded amps should rise a little
[22:41:37] <pfred1> I use an analog to test mine its easier to watch the needle
[22:41:41] <MrSunshine> k, have to check that tomorrow :)
[22:41:46] <MattyMatt> pfred1. Lunokhod2 drove 37km. that's the record for Opportunity to beat
[22:41:47] <MrSunshine> and gonna double check the cables also :)
[22:42:18] <pfred1> I think on Jones page he explains motor phasing
[22:42:33] <pfred1> http://www.cs.uiowa.edu/~jones/step/types.html
[22:47:35] <pfred1> MrSunshine taking a wild guess it almost sounds like your motors are suffering from resonance
[22:48:01] <pfred1> and just holding them makes them stop resonating so mush
[22:51:39] <pfred1> MrSunshine this looks like a pretty good page: http://www.piclist.com/techref/io/stepper/wires.htm
[22:52:56] <pfred1> MrSunshine check out the Bill Krause method about halfway into the page
[22:53:18] <frallzor> * frallzor needs to get rods for his e-chain rack tomorrow
[22:54:26] <JT-Hardinge> frallzor: what are you building?
[22:54:48] <pfred1> JT-Hardinge frallzor is making eBling!
[22:56:21] <frallzor> JT-Hardinge a mill =)
[22:56:33] <JT-Hardinge> it's big :)
[22:56:46] <frallzor> can 6x M6 in 2mm material hold like 1kg with forces from the side
[22:56:56] <frallzor> not just straight along the screws
[22:58:17] <pfred1> frallzor whats that in inches?
[22:58:50] <frallzor> 0.234 maybe
[22:59:02] <pfred1> * pfred1 knows a KG is about 2.2 pounds
[22:59:12] <frallzor> 2 threads will be in the material
[22:59:27] <pfred1> heck almost a quarter of an inch can hold up a couple of pounds no sweat
[23:00:07] <pfred1> if you really doubt it tap a piece of scrap and wail on it I bet it'd hold though
[23:01:12] <pfred1> ah material steel or aluminum?
[23:01:22] <frallzor> steel
[23:01:29] <pfred1> yeah i say go for it
[23:01:49] <frallzor> wont be any more force to it than its own weight practially
[23:01:53] <frallzor> just the e-chain
[23:02:14] <pfred1> I bet it'd hold over 100 kilos
[23:03:56] <pfred1> frallzor just don't strip it out in the process to prove me wrong OK?
[23:04:13] <frallzor> I will :P;)
[23:04:58] <pfred1> yes let me qualify done right I bet it'd hold over 100 kilos
[23:06:14] <pfred1> frallzor sounds to me like you should be using sheet metal screws or something for the application though
[23:10:03] <JT-Hardinge> Sweet! one more thing crossed off the list... one day the only thing left will be to make parts
[23:11:48] <pfred1> my list is so long I don't get too excited if I cross something off of it really
[23:12:31] <pfred1> * pfred1 did install a parallel port card today though ...
[23:13:00] <frallzor> * frallzor has reached a few milstones, every step now is exciting
[23:13:04] <frallzor> *mile
[23:13:15] <andypugh> MrSunshine: Where did you get your motors from? I bought some 8-wire motors and the data sheet was wrong...
[23:13:41] <pfred1> andypugh yeah i like this one guys test it sounds rather exhaustive and definitive to me
[23:13:58] <JT-Hardinge> my list is so short I can see the light at the end of the tunnel and I'm pretty sure it is not the train coming :)
[23:14:45] <pfred1> andypugh the Bill Krause says: about halfway down this page: http://www.piclist.com/techref/io/stepper/wires.htm
[23:14:47] <andypugh> I went through this myself....
[23:15:13] <andypugh> Wire the pairs in series. If you have the ends wrong then you get current and no torque...
[23:15:47] <andypugh> It doesn't matter is one pair is switched, you just end up with a reversed motor.
[23:15:58] <pfred1> yup
[23:16:28] <andypugh> Once you have identified the ends (using a bench power supply, not a stepper driver) you can wire in parallel.
[23:16:45] <pfred1> he can't his driver can't handle the current
[23:17:15] <pfred1> it's iffy that it runs his motor in series
[23:21:05] <andypugh> I was speaking in general terms...
[23:21:41] <pfred1> 18:35 < MrSunshine> pfred1, 1.8A max, motors are rated 2A 4V in serial mode
[23:22:05] <pfred1> so he's 200 ma shy of really running his motors in series even
[23:22:43] <pfred1> still as long as he didn't smoke his driver I'd think it'd run his motor correctly
[23:22:59] <pfred1> just not full power
[23:23:23] <pfred1> but series is high torque low speed right?
[23:23:24] <andypugh> Aye, I was just saying that the way to test is in series, even if you want to run in parallel. And you should use a generic PSU not the driver for the testing too, some drivers hate being disconnected powered up.
[23:24:17] <andypugh> It actually seems to make very little difference. I have one of my bigger steppers on a 7A driver in parallel and one on a 3.5A driver in series, and they run pretty much the same.
[23:24:31] <pfred1> huh
[23:25:23] <pfred1> I always heard parallel was the best performance
[23:25:39] <andypugh> You have a higher voltage ratio and a lower inductance in Parallel, so should get more speed, but I have not noticed that being a huge difference. And the driver cost is way higher.
[23:27:24] <pfred1> when i built my motor driver i had this strange deal where it'd run much better with less current
[23:27:49] <pfred1> motor is rated at 2A but I find it operates most smoothly at half that
[23:28:33] <pfred1> and its really finicky about it too
[23:28:51] <andypugh> That seems odd. I wonder if the driver is sending a weird pulse shape?
[23:28:56] <MrSunshine> andypugh, jb cnc .. www.brundin.biz i think it is .. tho its swedish :)
[23:28:58] <pfred1> like a little too much or a little too little really hurts how it runs
[23:29:13] <MrSunshine> http://www.brundin.biz/images/extra/STM76-185-wire-serial.jpg
[23:29:17] <MrSunshine> there is the wiring diagram
[23:29:42] <pfred1> MrSunshine don't tell me you're running in full step mode
[23:30:00] <MrSunshine> pfred1, no
[23:30:03] <MrSunshine> 1/8
[23:30:07] <pfred1> MrSunshine Ok good
[23:30:17] <pfred1> because full step is sort of oddball
[23:31:16] <andypugh> The "Expired" 716K one?
[23:31:20] <pfred1> MrSunshine if it were me I'd still work through phasing the motor just to make absolutely sure everything is as it should be
[23:32:14] <pfred1> MrSunshine BTW Sweedish is a lot like english
[23:32:53] <MrSunshine> pfred1, the wiring diagram is in english :)
[23:32:57] <pfred1> MrSunshine I always thought sweedish was more like hu durper duper du!
[23:33:00] <MrSunshine> tho the page is in swedish :P
[23:33:12] <MrSunshine> http://www.brundin.biz/product_info.php?products_id=3
[23:33:30] <andypugh> It is, I found that in Sweden. Lots of the words are the same, just generally the less "polite" version. Like "drag" means "pull" but in english you tend to only drag things that don't want to be pulled...
[23:33:36] <pfred1> MrSunshine now thats a recipie for sweedish meatballs if ever i saw one!
[23:34:42] <pfred1> how in the hell do countries operate with runes for their language?
[23:34:46] <andypugh> I had a motor with exactly the same wire colours, the data sheet was wrong...
[23:35:08] <pfred1> MrSunshine yeah man do the right thing ring it all out!
[23:35:41] <pfred1> MrSunshine unloaded it should run and you can't even hear it
[23:35:42] <JT-Hardinge> it's a small step for mankind with 5 tubbies of parts emptied and 3 more covers back in place on the Hardinge
[23:36:04] <JT-Hardinge> but one giant leap for me :)
[23:36:30] <pfred1> JT-Hardinge no its one small step for man one giant leap for mankind
[23:37:18] <pfred1> I forget what he was supposed to say he mucked it up though
[23:37:41] <JT-Hardinge> aww shit
[23:37:44] <pfred1> I guess if I flew to the Moon in a recycled TV dinner tray I'd be a little at a loss for words myself htough
[23:38:04] <andypugh> MrSunshine: It doesn't need to be a complex test. Do you have some sort of current-limited power supply?
[23:38:19] <pfred1> when they built the LEM they had to put pans on the floor because if you dropped a screwdriver it'd have gone right through it!
[23:38:33] <MrSunshine> andypugh, nop i dont :/
[23:38:47] <pfred1> andypugh a flashlight battery
[23:39:18] <andypugh> Just twist together the common ends of each pair, then apply current to the other ends and see if you get holding torque. Then switch the polarity and see if it jumps a step and gives torque again.
[23:39:32] <andypugh> A battery is a rather bad idea, as they are not at all current limited.
[23:39:45] <pfred1> MrSunshine just work through the instruacions on this page: http://www.piclist.com/techref/io/stepper/wires.htm
[23:40:14] <andypugh> Ah, no, ignore that last bit, a 1.5V battery will be perfectly safe.
[23:40:18] <pfred1> andypugh sure htey are a standard D cell can't put out more than 1500 ma
[23:40:47] <pfred1> and thats on a dead short!
[23:41:06] <andypugh> Are you sure about that?
[23:41:34] <andypugh> That seems to indicate that with a dead short it would take over an hour to discharge and that seems unlikely.
[23:42:17] <pfred1> then put a light bulb in line with it
[23:42:34] <pfred1> but I think it'd be completely safe to do
[23:42:53] <andypugh> The motor is 4V steady-state to the 1.5V battery will be perfectly fine.
[23:44:01] <pfred1> the last bench supply I built is variable voltage and current
[23:44:10] <pfred1> its pretty cool
[23:45:11] <pfred1> but to test out a stepper motor I'd still grab a dry cell
[23:45:48] <mikegg> my fav benchtop power supply is the PS from a PC
[23:45:58] <mikegg> the plug that goes to the MB has one green wire
[23:46:10] <pfred1> mikegg how do you adjust the voltage?
[23:46:20] <mikegg> ground it to the case and bam, you have 12 and 5 VDC
[23:46:30] <mikegg> oh
[23:46:36] <mikegg> resistors?
[23:46:53] <pfred1> mikegg lrn 2 linear
[23:47:33] <mikegg> ?
[23:47:41] <andypugh> mikegg: Not the PC power supply I bought, it would sulk if there wasn't the right load on every voltage.
[23:48:33] <skunkworks> so - is there a way to find the closest place a movie is playing? sort of a revearse movie lookup?
[23:48:35] <pfred1> yeah i thought PC supplies had to be loaded 10% for accurate regulation?
[23:48:57] <pfred1> skunkworks I think I've see that sort of a site on the net
[23:49:09] <skunkworks> I will keep looking
[23:49:16] <pfred1> mikegg this is the supply I built: http://hmin.tripod.com/als/andysm/drawings/supplies/ps2-30v.gif
[23:49:23] <pfred1> dead simple works a treat
[23:50:19] <mikegg> argh
[23:50:26] <mikegg> I never know how to read those things
[23:50:35] <mikegg> 5k6 != 5006 ohms
[23:50:39] <mikegg> right?
[23:50:43] <pfred1> 5600
[23:50:52] <mikegg> ahh
[23:51:06] <pfred1> they use the K as a decimal because dots get lost in crappy copies
[23:51:12] <andypugh> Read the prefix as a decimal point
[23:51:14] <mikegg> ahhhhhh
[23:51:44] <andypugh> Like a 28k6 modem
[23:51:47] <pfred1> here's my supply like that schematic: http://img713.imageshack.us/img713/2244/pict0579s.jpg
[23:52:43] <mikegg> which components need a heat sink?
[23:52:54] <mikegg> the 3055's?
[23:52:55] <pfred1> mikegg the power output transistors
[23:53:10] <pfred1> yeah i used some NEC jobbies I pulled out of a mini desk computer
[23:53:18] <mikegg> heheh
[23:53:21] <pfred1> any NPN power transistors work
[23:53:24] <mikegg> i love canibalism
[23:53:29] <mikegg> cool
[23:53:46] <pfred1> its basically al inear amplifier that plays one tune the juice song
[23:54:25] <pfred1> and in current limit mode its cool once you reach current limit it just keeps backing off the voltage
[23:54:47] <pfred1> so you can never exceed the set limit
[23:55:21] <mikegg> how do you switch modes?
[23:55:31] <pfred1> just a potentiemeter
[23:55:35] <mikegg> what did you gut the cap from
[23:55:37] <mikegg> oh, dud
[23:55:38] <pfred1> turn it up more current down less
[23:55:38] <mikegg> duh
[23:55:41] <mikegg> right
[23:55:52] <pfred1> oh i scrap everything
[23:56:09] <pfred1> old TVs stereos computers you name it
[23:56:49] <pfred1> BTW that high current diode in there for protection yo ucan get them out of PC switching supplues as back to back diode arrays
[23:56:56] <pfred1> every supply has one
[23:57:12] <pfred1> then just use one half of it and you're in
[23:57:52] <pfred1> here's me load testing that supply: http://img196.imageshack.us/img196/6414/pict0576h.jpg
[23:58:01] <pfred1> each bulb is eating like 2 amps
[23:58:47] <andypugh> I wonder what this lot is worth?
[23:58:49] <andypugh> http://cgi.ebay.co.uk/LARGE-AMOUNT-OF-MILLING-CUTTERS-AND-TOOLING_W0QQitemZ290415641021
[23:59:27] <pfred1> andypugh at flea markets i don't pay over $2 a cutter usually
